The second enforcement alert, "MSW Landfill Operators Fail to Include Wastes from Total Degradable Waste-in-Place and Properly Sample Landfill Gas, Resulting in Underreported Emissions," is intended to remind MSW landfill operators, owners and their consultants to properly identify and document nondegradable wastes excluded in calculations and to collect representative LFG samples for non-methane organic compounds analysis and emission calculations.
"After the hottest summer on record, the need to limit climate change is more critical than ever before," said EPA Assistant Administrator for Enforcement and Compliance Assurance David M. Uhlmann."Landfills are the third largest source of methane, a climate super pollutant that is 80 times more potent than carbon dioxide. Landfill owners and operators must meet their legal obligations to control methane emissions that contribute to global climate change-and EPA will hold them accountable if they fail to do so."
In 2022, the most recent year for which data is available, methane releases accounted for approximately 14.4 percent of total emissions. This is approximately equivalent to greenhouse gas emissions from more than 24 million gasoline-powered vehicles driven for one year or the carbon dioxide emissions from more than 13.1 million homes' energy use for one year.
Because methane is both a powerful greenhouse gas and short-lived compared to carbon dioxide, achieving significant reductions will have a rapid and significant effect on reducing the impact on climate change.At the same time, methane emissions resulting from MSW landfills represent a lost opportunity to capture and use a significant energy resource.
In August 2023, EPA announced its first-ever climate enforcement initiative - Mitigating Climate Change - as one of six National Enforcement and Compliance Initiatives(NECIs) for fiscal years 2024-2027. The new climate change initiative focuses additional resources on reducing emissions of the highest impact super-pollutants - hydrofluorocarbons (HFCs) and methane. Under the methane-focused component of the initiative, EPA is seeking to ensure greater compliance with environmental laws at oil and gas facilities and landfills.
Following on the mitigating climate change initiative, the EPA issued its "Climate Enforcement and Compliance Strategy" on Sept. 28, 2023. The strategy requires EPA's enforcement and compliance program to fairly and vigorously enforce the full array of EPA's climate rules, including greenhouse gas reporting requirements and limits on other climate pollutants such as carbon dioxide and nitrous oxide. The strategy also recognizes that while the impacts of climate change affect people in every region of the country, certain communities and individuals already overburdened by environmental stressors and with less access to the resources needed to adapt to and recover from climate change impacts are especially vulnerable.
The two alerts highlight EPA enforcement actions taken over the past several years to address noncompliance with the Clean Air Act requirements. For example:
